In December 2015 a very important piece of legislation – the Assisted Decision- Making (Capacity) Act, 2015 was passed by the Oireachtas and signed into law. The Act reforms Irelands capacity legislation which has been in place since the 19th Century and it establishes a modern statutory framework to support decision making by adults who have difficulty in making decisions without help. While it was expected the legislation would come into operation during 2016 unfortunately only a limited number of provisions of the Act have been commenced. This is a progressive and reforming piece of legislation and will be of immense assistance to vulnerable adults who are experiencing difficulties with decision making whether due to intellectual disabilities, acquired head injuries or old age.
